The conflict in Sierra Leone began in 1991 and still continues. It has led to over 50,000 deaths. The fighting has been characterised by the use of child combatants and widespread mutilation of civilians by amputation. When the conflict began, it would have seemed improbable that any UN response would include a forum for the trial of international crimes. After all, even the high tide of international enforcement of international criminal law, the Nuremberg International Military Tribunal, had begun to be excised from mainstream treatments of international law.1 The possibility of a permanent international criminal court had recently been revived, and sent to the International Law Commission for consideration, but the record of the ILC with controversial projects would not have led to an expectation of quick progress.2 Yet, nearly 10 years on, the UN is now involved in setting up a fourth criminal court,3 the “Special Court” for Sierra Leone. Despite the selectivity inherent in ad hoc reactions, and the continuing opposition to the Rome Statute in some quarters, it is now difficult to deny that progress is being made towards a new form of international criminal order where the improbability of prosecution for international crimes can ne longer be presumed.
